Heating and heat supply systems
Aurora Engineering designs heat supply systems for new and existing buildings: heat load calculation to EN 12831, heat generators from heat pumps and district heating to CHP, distribution networks with hydraulic balancing and surface heating systems, compliant with energy law and designed for low running costs.
Heat supply determines a building’s carbon footprint and running costs for decades. We compare generator options by life-cycle cost and design distribution networks that operate efficiently at low system temperatures.
Scope of services
What we design in heating
Heat load and energy demand
Room-by-room heat load to EN 12831, energy demand to DIN V 18599, compliance with the German Building Energy Act.
Heat generators

Frequently asked questions
Frequently asked questions about heating design
Heat pump or district heating: which is more economical?
It depends on district heating price, electricity tariff, building envelope and subsidies. We compare both options with real load profiles over 20 years and show the cost threshold transparently.
Does a heat pump work in an existing building?
In most cases yes, if emitters and hydraulics are converted to low flow temperatures. We check this room by room via the heat load and propose targeted adjustments.
Do you also handle subsidy applications?
We prepare the technical evidence and accompany the BEG application together with energy efficiency experts.
Designing or refurbishing a heat supply?
We compare generator options and show you the most economical path to decarbonisation.
